Rosemary medical bills

Rosemary is a 3 year old pit, she has been feeling down lately and looking a bit unwell after our first trip to vet and minus $300 nothing was resolved, and we took her to urgent care and unfortunately she had to have surgery due to some obstruction in the intestines, as more tests have to be done before surgery it has been tough. After 2 weeks she’s had surgery once,  X-rays, ultrasounds, and bloodwork quite a few times now every 2 days or so she’s being readmitted to the hospital with little to no change as she’s hardly eating anything and constantly throwing up whatever she does eat, her intestines and stomach are not working how they should be. During these tough times and unexpected events it has been rough trying to pay these bills since almost every trip comes back to $1000+ bill. Up to date we still don’t know what is wrong with her and are hoping to find a specialist to help her. We don’t want to let her down just because we can’t afford it so here we are asking for a helping hand, anything  is very very greatly appreciated.

Update: Rosemary passed away on 12/20/2020 after fighting hard and being constantly hospitalized she lost her battle and her body was slowly deteriorating, as per the vet they couldn’t figure out what was causing her body to shut down and believed it was due to genetics. We got our girl cremated and she came back home with us in Jan2021. 
we paid about $10k for all of her treatment and are currently paying off what is left which is $5k it’s been one long and rough emotional and financial rollercoaster. We’re still reaching out to try and get some help however little it is even if it’s a $1. It’s truly appreciated!
